The selection of cold storage panels is a core link that determines the construction quality, service life and operating cost of cold storage factories, and directly affects the temperature control stability,

With excellent corrosion resistance, high strength and stable performance, stainless steel is widely used in various industries.

In recent years, the minimalist decoration style has continued to prevail in the home improvement market. People's aesthetic for home spaces has gradually tended to be simple, high-grade and textured, and various new decorative materials have entered the public view.

304 stainless steel pipes are widely favored in industrial and civil fields for their excellent corrosion resistance. In comparison, 201 stainless steel pipes have poor anti-corrosion performance and are only suitable for dry indoor environments and low-standard engineering scenarios.

Bright annealing is a key heat treatment process for 304 stainless steel pipes, which can optimize the internal metallographic structure, eliminate internal stress, and ensure smooth and oxide-free surface of pipes.

Bright annealing is an essential heat treatment process to ensure the surface smoothness, corrosion resistance and mechanical properties of 304 stainless steel pipes. To achieve an oxide-free and mirror-bright surface, a series of strict process conditions including furnace tightness, temperature, air pressure and protective atmosphere must be fully controlled. The standard conditions for bright annealing of 304 stainless steel pipes are summarized as follows.
